High-strength wear-resistant hard alloy cutter bar
The invention relates to the technical field of cutter bar production, and discloses a high-strength wear-resistant hard alloy cutter bar prepared by the steps that: obtained metal tungsten is put in a ball mill and ground, and the tungsten fine powder obtained by grinding is mixed with ground and crushed carbon powder; and the mixture is put into an electric arc furnace, the temperature of the electric arc furnace is controlled to range from 800 DEG C to 1800 DEG C for reaction, continuous stirring is carried out in the process to ensure that the tungsten fine powder and the carbon powder are fully mixed, obtained solids are cooled, then the solids are continuously ground through a ball mill, the solids are put into a pressure rigid mold for mold forming, pressing is carried out under the pressure of 30-80 KSI, and thus the alloy cutter bar is prepared. 3% of an organic bonding agent, 4% of cobalt carbide and 1.5% of titanium carbide are added into the tungsten carbide powder, pressing is carried out under the pressure of 70 KSI, the relation between tungsten carbide is more precise favourably, and meanwhile the quality of the bar can be improved.
本发明涉及刀具棒材生产技术领域，且公开了一种高强度的耐磨硬质合金刀具棒料，通过将得到的金属钨放入到球磨机中进行研磨，将研磨得到的的钨精细粉，与研磨粉碎后的碳粉进行混合，投入到电弧炉内控制其温度为800℃‑1800℃之间进行反应，此过程中进行持续搅拌以确保钨精细粉与碳粉充分混合，将得到的固体进行冷却后继续使用球磨机研磨通过放入到压力刚性模具进行模制成型，通过采用30‑80KSI的压力进行压制，从而制成该合金刀具棒料本发明通过在加入到碳化钨粉中含有3％的有机粘合机以及4％的碳化钴和1.5％的碳化钛，通过70KSI的压力进行压制，有利于使得碳化钨之间的关系更为精密，同时能够提高该棒料的质量更高。
