混砂机刮板,与坚硬的砂子发生磨擦,要求刮板材料具有很高的抗磨能力。目前,混砂机刮板材料多为耐磨铸铁和经热处理的碳钢,有的在碳钢刮板底部镶橡胶带,旨在“以柔克钢”,效果都不够理想,每班磨损量高达0.5~2mm,维修更换又很不方便。为此,试用了两种新材料。 1.废旧合金刀片以碳钢作刮板基体,钢板厚20~30mm,弯曲前,在底边及端部铣一条深5~10mm的阶梯槽,然后将废旧合金刀片镶焊在刮板的阶梯槽中,这种刮板1986年开始在江西工业大学机
Mixer scraper, friction with the hard sand, scraper material requires a high anti-wear ability. At present, the sand mixer scraper material mostly cast iron and heat-treated carbon steel, and some in the bottom of the carbon steel scraper with rubber tape, designed to “soft grams of steel,” the effect is not ideal, the amount of wear per shift Up to 0.5 ~ 2mm, maintenance and replacement is very inconvenient. To this end, the trial of two new materials. 1. Scrap alloy blade carbon steel scraper substrate, steel thickness 20 ~ 30mm, before bending, in the bottom edge and end milling a deep 5 ~ 10mm step groove, and then the waste alloy blades in the scraper ladder set Groove, this scraper started in 1986 in Jiangxi University of Technology machine
