1. Hot rolling process

Hot rolling is a kind of raw materials through high temperature heating, and then through a number of rolling process, the billet processing into medium-thick plate process. In the hot rolling process, the raw material is first preheated by the heating furnace, so that the slab reaches the appropriate processing temperature. Then, through the hot rolling machinery and equipment for rolling, the slab will be gradually flattened and elongated, to get the required thickness and width. Finally, after cooling and shaping and other process steps, the final medium-thickness plate products.

2. Surface treatment process

After hot rolling process, the surface of hot rolled plate often has some oxidized layer and rust scale. In order to improve the quality and surface finish of the plate, often need to carry out surface treatment. Common surface treatment methods include pickling, shot blasting and polishing. Pickling is a method of removing surface oxidation and rust scale by immersion in an acid solution. Shot blasting is the use of sand blasting equipment to blast high-speed fluid particles to remove surface impurities. Polishing is by mechanical processing, the use of abrasives to polish the surface to improve the finish.

3. Edge cutting and cutting process

In order to get the size that meets the user's needs, it is often necessary to carry out edge cutting and cutting of hot rolled medium-thickness plates. Edge cutting is through the cutting machinery and equipment, the edge of the plate for excision, so that the edge is smooth and neat. Cutting is based on the user's size requirements, the plate will be cut into the specified size, in order to meet the user's needs at the same time, but also to improve the utilization rate of plate processing.

In short, hot rolled plate is a common and important metal material, widely used in various fields. By understanding the specification range and processing technology of hot rolled medium thick plate, this material can be better selected and utilized to meet the needs of engineering and production. At the same time, in the processing and use of the process, you also need to pay attention to the reasonable selection of materials and specifications to ensure its performance and safety.
