Special properties of high speed steel mould
工艺的完善性、紧密性造就水泥道牙钢模具模盒非凡的利用空间与市场需求是我们发展的唯一方向，目前国内的水泥道牙钢模具模盒制作工艺还不是很完善我们仍在继续努力实现水泥道牙钢模具模盒发展的新时期。水泥道牙钢模具模盒的制造一样通常都要颠末铸造、切削加工、热处置处罚等几道工序。为包管水泥道牙钢模具模盒的制造质量，低落生产本钱，其质料应具有精良的可锻性、切削加工性、淬硬性、淬透性及可磨削性;还应具有小的氧化、脱碳敏感性和淬火变形开裂偏向。
The only direction of our development is to make full use of thespace and market demand of the cement road teeth steel mold box. Atpresent, the manufacturing technology of the cement road teethsteel mold box in China is not perfect, but we are still trying torealize the new era of the development of the cement road teethsteel mold box. The manufacturing of the steel mould box for cementroad teeth usually goes through several processes such as casting,cutting and heat treatment. In order to guarantee the manufacturingquality and reduce the cost of production, the material should haveexcellent malleability, machinability, hardenability, hardenabilityand grindability, as well as small oxidation, decarburizationsensitivity and quenching deformation cracking tendency.
1、 可锻性具有较低的热锻变形抗力，塑性好，铸造温度范畴宽，锻裂冷裂及析出网状碳化物偏向低。
1. The forging property has low hot forging deformation resistance,good plasticity, wide casting temperature range, and low forgingcrack, cold crack and precipitation network carbidetendency.
2、退火工艺性球化退火温度范畴宽，退火硬度低且颠簸范畴小，球化率高。
2. The annealing process has a wide range of spheroidizingtemperature, low hardness, small bumping range and highspheroidizing rate.
3、切削加工性切削用量大，刀具消耗低，加工外貌粗糙度低。
3. It has the advantages of large cutting amount, low toolconsumption and low surface roughness.
4、氧化、脱碳敏感性高温加热时抗氧化怀能好，脱碳速率慢，对加热介质不敏感，产生麻点偏向小。
4. Oxidation and decarburization sensitivity when heated at hightemperature, the oxidation resistance is good, decarburization rateis slow, and it is not sensitive to heating medium, resulting insmall pitting.
5、淬硬性淬火后具有匀称而高的外貌硬度。
5. After quenching, it has a uniform and high appearancehardness.
6、淬透性淬火后能得到较深的淬硬层，接纳和缓的淬火介质就能淬硬。
6. After hardenability quenching, a deeper hardenable layer can beobtained, which can be hardened by accepting moderate quenchingmedium.
