Problems solved by technology

[0003] The steel plate can be recycled and reused, which is of great significance to sustainable development. The recycled waste steel plate usually has a thick rust layer on the surface. After the steel plate is recycled, the rust layer generally needs to be removed. However, the rust layer Usually the adhesion on the steel plate is strong, according to the conventional grinding and derusting in the prior art, not only the workload is large, the difficulty is relatively large, but the efficiency of derusting is low

Embodiment 1

[0043] See figure 1 A split type air scrap steel continuous descaling process, comprising the steps of:

[0044] S1, first use the uneven tap of the surface of the waste steel sheet, remove the larger rust layer, and make some show layers loose;

[0045] S2, reduce the intensity of the tap, and again tap the surface of the steel sheet to increase the looseness of rust layers;

[0046] S3, blowing split ball particles by blower, so that the bubble ball particles are brought into loose rust layer slits;

[0047] S4, after the steel sheet is heated, so that the outer surface of the bubble ball particles is dissolved, and gradually increase, while continuously cracking, the rupture of the bubble ball particles produce vibration and impact, thereby effectively loosen and remove rust layers. Rust semi-finished product;

[0048] S5, the semifinished product surface rust rust particles fall cleaned, and then subjected to conventional mechanical grinding semi-finished surface rust rust.

Abstract

The invention discloses a continuous gas-cracking derusting process for waste steel plates, which belongs to the field of steel plate derusting. A continuous air-cracking derusting process for waste steel plates uses two knocking actions to loosen the rust layer, and then removes the rust. Bubble ball particles are sent into the gap of the loose rust layer. Under the heating operation, after the bubble ball particles are heated, the air in the inner air-filled layer expands, thereby accelerating the overflow from the pre-split solid groove, causing the inner air-filled layer to burst as a whole. Occasionally, it will produce impact and vibration on the loose rust layer, which significantly reduces the difficulty of removing the rust layer. Compared with the existing technology, it can effectively improve the rust removal efficiency of the waste steel plate. After bursting, the fragments of the inner air-filled layer can also burst, thus presenting a phenomenon of continuous bursting, which significantly prolongs the impact on the rust layer and further improves the rust removal efficiency.

Description

Technical field [0001] The present invention relates to the field of steel sheets, and more particularly to a waste-rust-resistant process for waste steel sheets. Background technique [0002] Steel plates have large coverage and inclusive capabilities, which can be used as roof panels, cover materials and manufacturing containers, oil storage tanks, packages, trains, automotive housings, industrial furnace housings, etc. Crash and combination can be used as required to make various structural parts and mechanical parts, and welded steel can also be made to further expand the scope of use of steel sheets. Bending and punching can be made, made into boilers, containers, baffles, civilian utensils, appliances, and blank of welded steel sheets and cold-bending steels. Due to the above characteristics, the total output of the steel material is more than 50%. In order to meet the needs of large-scale basic construction, my country has grown sharply to steel plates in industrial produc...
