Description

A steel grating production system and method

technical field

The invention relates to the technical field of steel grating manufacturing, in particular to a steel grating production system and method.

Background technique

Steel grating is a kind of steel product that is cross-arranged with flat steel according to a certain spacing and cross bars and welded into a square grid in the middle. It is mainly used as a drain cover, a steel structure platform plate, and a steel ladder step plate. etc.; crossbars are generally made of twisted square steel. The steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties. The surface of the steel grating can be punched to increase the anti-skid performance, and the flat steel can also be made of I-type flat steel.

With the progress and development of human society, countries around the world have increased their investment in improving people's livelihood and strengthening national defense. Steel gratings are unparalleled due to their durability, convenient transportation and installation, low maintenance costs, long service life, recyclability and high cost performance. Advantages, widely used in various fields such as municipal engineering, road traffic, water conservancy facilities, petrochemical industry, mine construction, aerial work platforms, underground engineering, wharf seawalls, offshore platforms, ships, etc., especially the annual consumption of developed countries Tens of millions of tons. According to incomplete statistics, since my country promulgated the new industry standard of YB/T4001.1-2007 steel grating in July 2007, the production capacity of steel grating manufacturers in Jiangsu, Zhejiang and Shanghai alone has reached millions of tons.

At present, most of the existing processes of steel grating manufacturers in the world belong to traditional industries with high energy consumption, high noise, high labor intensity and labor-intensive. The production method of steel grating in my country and even in the world is still relatively backward. It is an industry with high energy consumption, huge noise, labor-intensive, high production cost, and large investment in production lines. At present, it is mainly divided into two production methods, one is production line production, the equipment power is 800 to 1200KVA, the annual output is 5000 tons, the total length of the equipment is more than 20 meters, and the total investment of a standard production line equipment (including auxiliary equipment such as transformer power distribution room cables and cooling towers) Reaching 5-6 million yuan; the other is a traditional small enterprise that relies entirely on manual work and single-station production, with low production capacity.

Since 2005, China's steel grating output has been among the top in the world. In 2008, my country's steel grating products exported to the United States amounted to 90 million US dollars. After the 145.18% anti-dumping duties were imposed by the United States and the European Union, the national production lines shrank from more than 500 to more than 200 production lines in normal production.

There are two methods of making steel grating: machine pressure welding and hand-made.

Machine pressure welding uses a high-voltage resistance pressure welding machine. The manipulator automatically places the crossbars horizontally on the evenly arranged flat steel, and press-welds the crossbars into the flat steel through strong electric welding power and hydraulic pressure, so that the solder joints can be strong. High-quality steel grating with high stability and strength.

The welding process is affected by the matching of equipment and current and voltage. Generally, the welding strength of double rods is higher than that of single rods. This welding process is also related to the height of the raw flat steel. A large error in the width of the flat steel may affect the welding strength and make the strength inconsistent. ; The defects of this process are false welding and false welding, which can easily make the cross bar peel off.

Due to the rated capacity of the equipment, the welding process cannot produce heavy-duty steel gratings with large cross-sections. If the rated capacity of the welding process equipment is lower than 800KVA, it can generally only make flat steel gratings with a thickness of less than 4mm, and if it is 1250KVA, it can generally make flat steel gratings with a thickness of 5-6mm. Therefore, the process consumes a lot of electricity and the production cost is high.

Hand-made steel gratings include press-locking, welding, interlocking and welding-free, etc. The handmade welded steel grating is to punch holes or notches on the flat steel first, and then put the crossbar into the hole for spot welding. There will be gaps between the crossbar and the flat steel, and each contact point between the crossbar and the flat steel will For welding, the dense crossbars can also be spot welded. Although the production process is relatively flexible, the products are diversified, and it can basically produce a full range of steel gratings. It has advantages in heavy duty, but because the welding is all manual welding, it is easy to weld weakly, miss welds, and false welds, resulting in false welds and Missing welds reduce strength.
