一、Customer requirements

　　Anti corrosion and derusting of steel bar surface, current products and ratio S280: G25 = 4:6

二、Formula recommended by our company

　　The use of alloy steel shot S280 and alloy steel sand G25 in 6:4 ratio can achieve the effect of sand cleaning and rust removal, while saving costs.

　　Note: when the steel sand ratio is high, the surface roughness of the treated steel bar is high, the adhesion of the surface coating will be enhanced, but the coating used will increase, and the cost will be high. Your company can increase the use proportion of steel shot according to the requirements of the steel surface to reduce the whole cost. If the coating (paint) required by your company has strong adhesion, the previous proportion can also be continued.

　　Shot characteristics: mainly to control the surface finish

　　Horsepower steel shot S280 alloy cast steel shot, with fast cleaning speed, good anti elasticity, long service life and low consumption; moderate hardness, good toughness and recyclable use of steel shot; strict quality management process, so that the steel shot quality can achieve the best effect. Applicable equipment includes: q3110 roller shot blasting machine, q326 crawler shot blasting machine, Q378 hook shot blasting machine, large through shot blasting machine, steel plate pretreatment line, cleaning of sand blasting room, etc.; the company's products are carefully protected by double-layer coating, moisture-proof, waterproof and anti-corrosion packaging bags.

　　Characteristics of steel sand: mainly to control the surface roughness

　　G25 angular steel sand of HP steel shot is broken from alloy steel shot, hypereutectoid steel water chestnut shape, with characteristics of high hardness, strong toughness, strong impact resistance, thorough cleaning of workpiece, etc., which can be used repeatedly, and always maintain the angular angle in the sand blasting process. Its main applications include: surface treatment before spraying alloy castings, spring strengthening, sand cleaning and rust removal of small stainless steel castings, which are widely used in bridge and ship industries.
