Summary:The invention discloses a coating for a metal mold of a centrifugal machine. The coating is prepared from the following components by weight: 100 kg of zircon powder, 6-8 kg of sodium bentonite, 15-20 kg of silica sol, 4-5 kg of aluminum dihydrogen phosphate and 110-120 kg of water. The coating is good in heat-conducting property and is firmly bonded with a metal mold, so that a cast steel ingot is free of sand holes and high in smoothness. 本发明公开了一种离心机金属模具的涂料，由如下组分按重量配比制成：锆英粉100千克，钠基膨润土6-8千克，硅溶胶15-20千克，磷酸二氢铝4-5千克，水110-120千克。该涂料导热性能好，与金属模具粘接牢固，使所浇铸的钢锭无砂眼，光滑度高。
