Description

A kind of high silicon cast iron ingot mold

Technical field:

The utility model relates to the technical field of molds for continuous casting of iron alloys, in particular to a high-silicon cast iron ingot mold.

Background technique:

Ferroalloys are the most important deoxidizers and element additives in steelmaking. At present, the ferroalloy solidification forming process mainly used at home and abroad is crushing after pouring layer by layer in the casting bed. This process has high labor intensity, low degree of mechanization, and severe alloy powdering during the crushing process, which greatly reduces the production efficiency and economic benefits of ferroalloy enterprises. .

Utility model content:

The purpose of the utility model is to avoid the existing technical defects and propose a high-silicon cast iron ingot mold. Thereby, the problems existing in the prior art are effectively solved.

The purpose of this utility model can be realized by adopting the following technical solutions: the high-silicon cast iron ingot mold described is characterized in that it comprises a high-silicon cast iron mold body with an integrated structure, and the mold body is divided into a honeycomb structure by convex ribs A plurality of casting cavity modules are connected to each other through the flow iron groove above them, and fixing holes are arranged at both ends of the mold body.

The inside of the casting cavity module is a tapered structure, the maximum diameter is 50mm-70mm, the depth is 40mm-60mm, and the camber angle α of the mold walls on both sides is 25-30°. Realize automatic demoulding after alloy solidification.

The section of the flow iron trough is a trapezoidal structure, the width of the top is 45mm-65mm, the width of the bottom is 20-40mm, and the depth is 5-10mm.

The chemical composition of the high-silicon cast iron used in the mold body is calculated by mass percentage: 0.8-1.0% C, 14-18% Si, 4.0-6.0% Cu, 1.0-3.0% Cr, 0.4-0.6% Mo, 0.8- 1.0% Ce, the rest is Fe and impurities.

The beneficial effects of the utility model are: the high-silicon cast iron ingot mould, which can obtain iron alloy ingots with reasonable particle size at one time, eliminates the crushing link and reduces the alloy pulverization rate, greatly improves production efficiency and effectively saves resource.

Fig. 3 is a schematic diagram of the utility model used in ferroalloy continuous casting equipment.

As shown in the figure: 1. mold body; 2. mold wall; 3. casting cavity module; 4. flow iron groove; 5. convex rib; 6. fixing hole.

Detailed ways:

Below in conjunction with the preferred embodiment shown in accompanying drawing, be described in further detail:

As shown in Figures 1 to 3, the described high-silicon cast iron ingot mold is characterized in that it includes a high-silicon cast iron mold body 1 with an integrated structure, and the mold body 1 is divided into a plurality of honeycomb structures by convex ribs 5. Casting cavity 3 modules, multiple casting cavity 3 modules communicate with each other through the flow iron groove 4 above them, and the two ends of the mold body 1 are also provided with fixing holes 6 .

The inside of the casting cavity module 3 is a conical structure, the maximum diameter is 50mm-70mm, the depth is 40mm-60mm, and the camber angle α of the mold walls 2 on both sides is 25-30°. Realize automatic demoulding after alloy solidification.

The section of the flow iron trough 4 is a trapezoidal structure, the top width is 45mm-65mm, the bottom width is 20-40mm, and the depth is 5-10mm.

The chemical composition of the high-silicon cast iron used in the mold body 1 is calculated by mass percentage: 0.8-1.0% C, 14-18% Si, 4.0-6.0% Cu, 1.0-3.0% Cr, 0.4-0.6% Mo, 0.8 ~1.0% Ce, the balance is Fe and impurities.

The high-silicon cast iron ingot mold mentioned above, when implemented, its multiple casting cavity modules are connected to each other by the flow iron groove above to ensure that the alloy liquid can be completely filled during casting; the iron alloy melt is directly solidified in the ingot mold to a particle size Reasonable ferroalloy ingot casting, thus avoiding the crushing link in the traditional production process. Installing the high-silicon cast iron ingot mold on an iron casting machine can realize the continuous casting production of iron alloy. The alloy liquid is continuously cast into the high-silicon cast iron ingot mold installed on the transmission chain belt. The liquid alloy solidifies rapidly in the ingot mold and runs to the demoulding point. The ingot falls off and enters the collecting basket. The ingot is crushed to obtain a granular ferroalloy product.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
