The invention relates to a method for manufacturing a graphite disc sintered by hard alloy, which belongs to the technical field of hard alloy sintering, and adopts the following forming agents in percentage by weight: 50-60% of organic solvent, 20-25% of polyacrylic resin, 8-15% of paraffin, 3-5% of cross-linking agent, 2-5% of dispersing agent, 5-8% of water repellent agent, 1-2% of CPP (Chlorinated Polypropylene) and the like. The hard alloy mainly comprises brittle powder such as indissolvable metal tungsten carbide and the like, so that the hard alloy is difficult to form by using a conventional forming process, and can be formed only by adding some organic solvents as forming agents. Compared with products in the same industry, the manufacturing method of the graphite boat in the hard alloy sintering field can achieve the purposes of being long in service life and small in poor product bending.
一种硬质合金烧结的石墨盘的制作方法，属硬质合金烧结技术领域，采用的成型剂配比为：有机溶剂50‑60％、聚丙烯酸树脂20‑25％、石蜡8‑15％、交联剂3‑5％、分散剂2‑5％、疏水剂5‑8％、CPP1‑2％等。因硬质合金主要由难溶金属碳化钨等脆性粉末组成，用较常规的成型工艺难以成型，需要加入某些有机溶剂作为成型剂才能成型。该硬质合金烧结领域的石墨舟皿的制作方法，相比于相同行业的产品，能达到使用寿命长，产品弯曲不良少的目的。
