Hot rolled pickling plate

Hot rolled pickling coil is made from slab (mainly continuous casting billet), which is heated and made into strip by roughing mill and finishing mill. The hot steel strips from the finishing mill are cooled to the set temperature by laminar flow and then rolled into steel strip coils by the coiler. The cooled steel strip coils are removed from the surface of the steel sheet after pickling.

classification

Hot rolled pickling steel plate products include steel strip (coil) and steel plate made by cutting thereof. The steel belt (coil) can be divided into straight coil and finishing coil (split coil, flat coil and slitting coil).

use

The way is very wide, mainly used in: petrochemical equipment, automobile industry, household appliance industry, agricultural vehicle industry, shipbuilding industry, tower industry, steel structure industry, transportation facilities industry, environmental protection machinery, textile machinery, containers, lighting equipment, agriculture and animal husbandry machinery, harvester, cold-formed steel, installation companies, etc. Light industrial appliances, mainly used in the manufacture of compressor shell (upper and lower shell), bracket, water heater liner and other chemical oil drums. Other industries such as bicycle parts, motorcycle industry (stamping parts), all kinds of welded pipes, electric cabinets, highway guardrail, supermarket shelves, warehouse shelves, fences, iron ladder and various shapes of stamping parts. Quality characteristics of pickling plate: surface morphology, stamping performance. At present, the industry with the largest consumption of pickling plate is compressor industry and bracket, followed by bicycle. Other industries for machinery, shelf elevator can be used.

Regular brand

General carbon is usually Q235B, SPHC (C material) SPHD SPHE SS400 SS330 SS490 SS540, DP540, DP590. SAPH370 SAPH400 SAPH440, low alloy S420MC, S460MC and QSTE420TM~QSTE550TM, wheel steel 380CL~590CL and beam steel 510L~510L700L, etc.

Brand distinction

Q235B: more widely used, the customer refers to the general roll or A3 plate are said to be this kind of material, bending performance and stamping performance is poor, used for welding.

SPHC (C material) : This kind of material is softer than Q235B and has better bending performance. It can be used for stamping of mechanical parts, but the stamping degree is limited.

SPHD (hot rolling for stamping) SPHE (hot rolling for deep drawing) SS400: This kind of material is harder than Q235B, which is better for load-bearing or plate surface.

The main uses of hot rolling and pickling in the automobile industry are as follows: automobile chassis system, including girders, auxiliary girders, etc. Wheels, including rims, wheel radiators, etc. Filter and hinge cockpit panel. Carriage board, mainly the floor of various trucks. Other stamping parts, including anti-collision bumpers, brake interlock sleeve and some car internal small parts.
