热处理由钢和其它材料制成的片材和其它产品的炉是已知的，其包括，例如，形状多样的辐射管，例如形状为“P”、“S”、“I”、双“P”、“M”或双“U”形。Furnaces for heat treating sheet and other products made of steel and other materials are known, which include, for example, radiant tubes of various shapes, such as "P", "S", "I", double "P ”, “M” or double “U” shape.
所述辐射管由炉壁支撑，一侧由连接法兰支撑，另一侧由辐射管背部支撑件支撑，所述辐射管背部支撑件设置于固定在炉壁上的炉座的表面上。The radiant tube is supported by the furnace wall, one side is supported by the connecting flange, and the other side is supported by the radiant tube back support, and the radiant tube back support is arranged on the surface of the furnace seat fixed on the furnace wall.
辐射管背部支撑件与炉座表面之间的相互作用使得可以补偿由温度变化引起的辐射管的活动。The interaction between the radiant tube back support and the surface of the furnace bed makes it possible to compensate for the movement of the radiant tube caused by temperature changes.
炉所达到的平均在700℃和1200℃之间的高温造成了辐射管背部支撑件与所述表面粘合的问题，导致辐射管“粘连”，进而导致辐射管折断。The high temperatures reached by the furnace, averaging between 700°C and 1200°C, cause problems with the bonding of the radiant tube back supports to the surface, causing the radiant tubes to "stick", which in turn causes the radiant tubes to break.
WO-2011/044599描述了一种辐射管，其辐射管背部支撑件通过可更换滑动平面设置于炉壁上的炉座表面。WO-2011/044599 describes a radiant tube whose radiant tube back support is arranged on the furnace bed surface on the furnace wall via replaceable sliding planes.
US-4520789示出了带有法兰的辐射管，其具有一凹处，与固定在炉壁上的管状臂滑动连接。为了限制过热，所述管状臂被涂覆绝热材料。US-4520789 shows a flanged radiant tube having a recess for sliding connection with a tubular arm fixed to the furnace wall. In order to limit overheating, the tubular arms are coated with insulating material.
WO-2014072839描述了一种具有辐射管背部支撑件的辐射管，其辐射管背部支撑件具有设有防粘连装置如滚动装置，或者涂层(包括低摩擦材料，或者碳钨或锆基热处理材料，或者任何具有给定的粗糙度的其它材料，或者硬化材料)。WO-2014072839 describes a radiant tube having a radiant tube back support with anti-sticking means such as rolling means, or coatings (including low friction materials, or carbon tungsten or zirconium based heat treatment materials) , or any other material with a given roughness, or hardened material).
JP-8327263描述了一种低摩擦系数涂层，该涂层被施加到与炉支撑壁接触的热交换器的部分以防止粘连现象。JP-8327263 describes a low coefficient of friction coating that is applied to the parts of the heat exchanger that are in contact with the furnace support walls to prevent sticking phenomena.
US-7678465描述了一种包含氧化锆的防粘连涂层，用于承受高温的钢。US-7678465 describes an anti-block coating comprising zirconia for steel subjected to high temperatures.
WO-99/14400描述了一种包含涉及锆的保护涂层的热交换器。WO-99/14400 describes a heat exchanger comprising a protective coating involving zirconium.
缺点在于，WO-2011/044599中描述的滑动平面易受到磨损，因此必须停炉替换，炉需要被冷却然后再次加热。类似的问题也涉及WO-2014072839中描述的滚动装置。A disadvantage is that the sliding planes described in WO-2011/044599 are subject to wear and must therefore be shut down for replacement and the furnace needs to be cooled and then heated again. A similar problem also concerns the rolling device described in WO-2014072839.
另一方面，辐射管背部支撑件涂层被广泛使用，在所有情况下这意味着辐射管背部支撑件使用的补充工作，也意味着更多的研究费用来寻找合适的涂层，在所有情况下，涂层在给定数量的工作循环之后都将受到磨损。On the other hand, radiant tube back support coatings are widely used, which in all cases means supplementary work for the use of radiant tube back supports, and also means more research costs to find suitable coatings, in all cases However, the coating will be subject to wear after a given number of duty cycles.
本发明的目的是制造一种辐射管，其用于热处理钢和其它材料制成的片材和其它产品的炉，其具有辐射管背部支撑件，所述辐射管背部支撑件不会粘连到固定在炉壁上的炉座表面，其容易制造，不会磨损，可以获得较长的工作周期而不需要熄灭炉。The object of the present invention is to make a radiant tube for use in furnaces for the heat treatment of sheets and other products made of steel and other materials, having a radiant tube back support which does not stick to a fixed The surface of the furnace seat on the furnace wall, which is easy to manufacture, does not wear out, and makes it possible to obtain a long duty cycle without extinguishing the furnace.

用于热处理钢和其它材料制成的片材和其它产品的炉的辐射管1具有双“P”形，中央导管2通过两个配件4、5(图1-3)与两个侧导管3连通。Radiant tubes 1 of furnaces for heat treatment of sheets and other products made of steel and other materials have a double "P" shape, with a central duct 2 passing through two fittings 4, 5 (Fig. 1-3) and two side ducts 3 connected.
第一配件4位于辐射管1的第一末端，并通过法兰6固定在炉的侧壁(图中未示出)上，使热的加热流体流入/流出辐射管1。The first fitting 4 is located at the first end of the radiant tube 1 and is fixed to the side wall (not shown in the figure) of the furnace by means of a flange 6 to allow hot heating fluid to flow into/out of the radiant tube 1 .
管状辐射管背部支撑件7，适当地设置于固定在炉的第二侧壁上的炉座8的表面81上，外部固定在第二配件5上(图4)。The tubular radiant tube back support 7, suitably arranged on the surface 81 of the base 8 fixed on the second side wall of the furnace, is externally fixed on the second fitting 5 (Fig. 4).
辐射管背部支撑件件7具有波纹外表面71，即其经过波纹处理。The radiant tube back support piece 7 has a corrugated outer surface 71, ie it is corrugated.
所述外表面71沿着所述辐射管背部支撑件7的滑动轴线L的方向具有依次交替的一系列突起72和凹部73，所述轴线L与管状辐射管背部支撑件7的轴线重合，并且相对于炉的所述侧壁正交。特别地，所述轴线L表示辐射管背部支撑件7在炉座8的表面81上的主要滑动方向，辐射管背部支撑件7能够沿着更多的方向滑动，尽管在所有情况下这些相对于轴线L都是次要的.The outer surface 71 has a series of protrusions 72 and recesses 73 alternating in succession along the direction of the sliding axis L of the radiant tube back support 7, said axis L being coincident with the axis of the tubular radiant tube back support 7, and Orthogonal with respect to said side walls of the furnace. In particular, said axis L represents the main direction of sliding of the radiant tube back support 7 on the surface 81 of the base 8, along which the radiant tube back support 7 can slide in more directions, although in all cases these are relative to Axis L is secondary.
优选地，波纹间距(即，两个连续的突起72或两个连续的凹部73之间的距离)包括在35mm与45mm之间，并且凹部73的深度(突起72的顶点721与凹部73的底部731之间的距离)大于或等于1mm，优选在2.5mm和3.5mm之间。Preferably, the corrugation pitch (i.e. the distance between two consecutive protrusions 72 or two consecutive recesses 73) is comprised between 35 mm and 45 mm, and the depth of the recesses 73 (vertex 721 of the protrusion 72 to the bottom of the recess 73 731) greater than or equal to 1mm, preferably between 2.5mm and 3.5mm.
更优选地，波纹间距(两个连续的突起72或两个连续的凹部73之间的距离)为约40mm，并且凹部73的深度(突起72的顶点721与凹部73的底部731之间的距离)为约3mm。More preferably, the corrugation pitch (the distance between two consecutive protrusions 72 or the distance between two consecutive recesses 73) is about 40 mm, and the depth of the recesses 73 (the distance between the apex 721 of the protrusion 72 and the bottom 731 of the recess 73 ) is about 3mm.
优选地，辐射管背部支撑件7的长度在250mm和350mm之间。Preferably, the length of the radiant tube back support 7 is between 250mm and 350mm.
甚至更优选地，辐射管背部支撑件7长约300mm。Even more preferably, the radiant tube back support 7 is about 300mm long.
根本上，重要的是凹部73的深度必须大于或等于1mm，以允许辐射管背部支撑件7仅在突起72的顶点721接触到炉座8的表面81：这样，接触是点状的，从而避免了粘连现象。交替的一系列突起72和凹部73的存在意味着辐射管背部支撑件7可以在炉膛8的所述表面81上滑动而不会粘连，特别是所述辐射管背部支撑件7可以主要沿着滑动轴线L的方向滑动。更浅的深度不能防止在很高的温度下的粘连。Fundamentally, it is important that the depth of the recess 73 must be greater than or equal to 1 mm to allow the radiant tube back support 7 to touch the surface 81 of the base 8 only at the apex 721 of the protrusion 72: in this way, the contact is point-like, thereby avoiding adhesion phenomenon. The presence of an alternating series of protrusions 72 and recesses 73 means that the radiant tube back support 7 can slide on said surface 81 of the furnace 8 without sticking, in particular that said radiant tube back support 7 can slide mainly along Sliding in the direction of the axis L. Shallower depths do not prevent sticking at very high temperatures.
优点在于，凹部的深度使得可以具有足够的空间来容纳炉内可能的炉渣。此外，辐射管背部支撑件7设置通孔75以允许释放可能在封闭室中产生的可能的过热；优选地，辐射管背部支撑件7包括四个以90°设置的通孔75。The advantage is that the depth of the recess is such that there is enough space to accommodate possible slag in the furnace. Furthermore, the radiant tube back support 7 is provided with through holes 75 to allow the release of possible overheating that may arise in the closed chamber; preferably, the radiant tube back support 7 comprises four through holes 75 arranged at 90°.
在上面所示的实施方式中，辐射管背部支撑7没有任何涂层：其仅在辐射管1的制造步骤中波纹化。In the embodiment shown above, the radiant tube back support 7 does not have any coating: it is only corrugated during the manufacturing step of the radiant tube 1 .
为了限制辐射管背部支撑体7过热，可以涂覆绝热材料，该绝热材料包括氧化锆(重量百分比高于90％)和氧化钇(重量百分比低于10％)。In order to limit overheating of the radiant tube back support 7, it is possible to coat a heat insulating material comprising zirconia (more than 90% by weight) and yttrium oxide (less than 10% by weight).
所述物质在辐射管背部支撑件7和炉座8的表面81之间形成热屏障。Said substance forms a thermal barrier between the radiant tube back support 7 and the surface 81 of the furnace bed 8 .
在一个实施方案中，所述物质包含92％重量的ZrO2和8％重量的Y2O3。In one embodiment, the material comprises 92% by weight ZrO2 and 8% by weight Y2O3 .
优点在于，所述物质具有10至15之间的孔隙率百分比(以重量计)、500至600之间的显微硬度(HV300)、高于8MPa的结合能力并且赋予喷涂表面7至8μηι之间的粗糙度(Ra)。The advantage is that the substance has a porosity percentage (by weight) between 10 and 15, a microhardness (HV 300 ) between 500 and 600, a binding capacity higher than 8 MPa and imparts a spray surface of 7 to 8 μm The roughness (Ra) between.
此外，所述物质增强了辐射管背部支撑件7在高温下的耐腐蚀性。Furthermore, the substance increases the corrosion resistance of the radiant tube back support 7 at high temperatures.
两个加强翼片10，相对于辐射管背部支撑件7的轴线倾斜地安装，用来提高辐射管背部支撑件7的坚固性。Two reinforcing fins 10 are installed obliquely with respect to the axis of the radiant tube back support 7 to increase the firmness of the radiant tube back support 7 .
图6-10示出了根据本发明的辐射管1的更多实施方式，其形状为“P”、“S”、“I”、“M”和双“U”，其具有一个或多个如权利要求中所述的辐射管背部支撑件7。Figures 6-10 show further embodiments of radiant tubes 1 according to the invention, having the shapes "P", "S", "I", "M" and double "U" with one or more A radiant tube back support 7 as described in the claims.
