Anchor steel is commonly used variety of coal mining enterprises,and the demand is bigger,better economic benefit,but in XinJiang and the northwest region,Without this product production enterprise?Xinjiang coal mining enterprises to use anchor steel are buying from China mainland?To meet the market demand and northwestern,promote the development of local economy,BaYi iron and steel mining anchor steel development plan is worked out.Anchor steel standard explicitly pointed out that,without Strong longitudinal ribbed rebar and anchor bolt can be used of HRB335 steel composition and performance requirements,Standard specifies its appearance shape style and requirements,but not provided specific size specification.Therefore,based on the characteristics of BaYi iron and steel rolling their own production capacity and production lines,in this article,through reasonable design of the chemical composition of steel,on the basis of reference for mainland companies anchor steel size,the groove design,parameter design of cross rib and rolling technology,and made the corresponding internal control standard.Successfully developed hot-rolled left-handed and right-handed mining anchor steel and batch production,meet the requirement of users..BaYi iron steel successfully occupied the market,fill the gaps in the product in the XinJiang region,made certain contribution to the ascension of BaYi steel benefit. |
