Abstract
The present invention belongs to the field of steel surface descaling technology, and is especially high pressure water shot blasting descaling method for wire, bar and belt of stainless steel or carbon steel in cold state. The technological process includes the following steps: compounding grinding material, purifying water, mixing and pressurizing, and jetting to descale. The present invention is one physical process to peel off oxide scale from the surface of steel, and has simple process, small covered area, reuse of the waste liquid, low cost, less environment and wide application.
Description
Technical field
The invention belongs to steel surface technique of scale removal field, particularly relate to a kind of wire rod, bar and band steel high pressure water shot blasting descaling method of cold stainless steel/carbon.
Background technology
Along with fast development of national economy, the social demand amount of steel such as stainless steel is increasing, because the surperficial de-scaling of will carrying out that the hot-rolled product that steel mill provides has before the user uses is handled, promptly removes scale on surface.Domestic traditional descaling process generally adopts sulfuric acid, hydrochloric acid (carbon steel) or nitric acid, hydrofluoric acid (stainless steel) as medium at present, and spent acid and toxic emission have produced serious environmental pollution.Domestic and international many researchers just are being devoted to the research and development of anacidity de-scaling, to substitute traditional pickling descaling method, as electrolysis de-scaling, laser de-scaling, grinding de-scaling, rotoblasting, alternating bending descaling method etc.So far, the big production that is used for wire rod, bar and the band steel of cold stainless steel/carbon of the method for domestic above-mentioned anacidity de-scaling yet there are no report.
Summary of the invention
The object of the present invention is to provide that a kind of operating cost is low, wire rod, bar and the band steel high pressure water shot blasting descaling method of de-scaling rate height, cold stainless steel/carbon that iron loss is few.
The objective of the invention is to adopt that such processing step method realizes is: the water purification-mixing pressurization-injection de-scaling of abrasive material preparation-source; The content of each processing step is:
Abrasive material preparation: adopt mortar preparation abrasive material, grains of sand size in the abrasive material: 10～80 orders; Husky water concentration 30～50%, the abrasive material that configures is stand-by;
Source water purifies: gets river or river and makes source water, and source water turbidity: 50～1000mg/L, water turbidity after purified treatment :≤5mg/L, it is stand-by to deposit the pond in;
Mix pressurization: with high-pressure pump stand-by abrasive material and the water after the purified treatment are mixed, mixed fluid pressure: 40～55Mpa, shower nozzle adopts the ruby material;
Spray de-scaling: spray de-scaling and in descaling device, carry out, this device is made of De-scaling box, shower nozzle and observation panel, treat that the dephosphorization steel are placed in the De-scaling box, high pressure mixing liquid is ejected into steel surface by shower nozzle, the distance of shower nozzle and steel is: 100～150mm, spray angle: 10～30 °, spray effective width and be: 30～50mm, with the steel after the de-scaling from De-scaling box, takes out, drying gets final product.
Waste liquid reclaims: the waste liquid after spraying de-scaling recycles abrasive material and water after precipitation process;
Because the present invention adopts high pressure mixing liquid to be ejected into the descaling method of steel surface, it is a kind of physical method that makes steel surface iron scale and matrix separate and strip down, its technology is simple, occupation of land is few, its waste liquid can be recycled, overcome and adopted the defective of the expensive and contaminated environment of pickling de-scaling, thereby had good marketing prospect.
The specific embodiment
