The hot -rolled steel plate is used as a raw material with a connected plate or a first rolling plate. After the step -in heating furnace heated, the high -pressure water is removed and entered the rolling machine.Control the rolling. After the final rolling, it passes through the cooling (computer control the cooling rate) and the rolling machine roll and become straight hair rolls.
Hot -rolled steel plate specifications
Size specifications: The width of the steel can also be any size of 50mm or 10mm multiple.Any size of the steel plate length is 100mm or 50mm multiple, but the minimum length of the thickness of the 4mm steel plate shall not be less than 1.2m, and the minimum length of the thickness of the steel plate shall not be less than 2m.As required, the thickness interval of a thickness of less than 30mm can be 0.5mm.
Hot -rolled steel plate price
1. Foshan stainless steel metal material hot -rolled steel plate specifications are 10*10 cm market price of 15 yuan.2. The specifications of Hongtu hot rolled steel plates are 10*10 cm market price of 17 yuan.3 Chenhao hot -rolled steel plate specifications are 10*10 cm market price of 21 yuan.
The difference between cold -rolled steel plate and hot -rolled steel plate
Cold-rolled plates are products that are rolled after rolling at room temperature after the hot rolling acid is washed. It has high-precision surface structure and high-precision thickness tolerance. Generally, cold-rolled thickness products are 0.2mm-3.0mm hot rolled plate.After heating, the billet is rolled under soft state. The surface becomes hot rolled rolling rolling rolling rolling rolling rolling, the oxygen iron skin, the surface quality is poor, the thickness of the thickness tolerance is large, and the thickness range is usually in the production of 2.0mm-20mm plate production.The process is: ironmaking-steelmaking-casting-hot-rolled-pickled-cold-rolled-galvanized-coloring, each module can become a product that can be sold directly.The hot -rolled plate is usually produced thick and the surface accuracy is not high. Usually it is necessary to pick up the rear channel, wash the iron oxide skin and then paint the surface paint.Cold rolling does not require acid washing. After processing, it can be directly subtracted and sprayed. There is also a product between cold rolling and hot rolling called hot rolling pickles.
