Botou casting company Skandia - cold resisting pattern causes and measures

 Botou casting company Skandia - cold traps, because waterlines and other measures Name: Splice (butt), waterlines. Features: low temperature metal flow each butt fusion but the emergence of cracks, irregular linear, there are two kinds of penetration and do not penetrate, there are trends in the role of external forces. Reason: 1, the molten metal pouring temperature is low or the mold temperature is low. 2, alloy composition does not meet the standards, poor mobility. 3, sub-unit filled with liquid metal, fusion is bad. 4, gate irrational process is too long. 5, filling speed is low or poor venting. 6, lower than the pressure. Remedy: 1, an appropriate increase in pouring temperature and mold temperature. 2, changing the alloy composition, improve liquidity. 3, improved gating system, increase the speed of the gate, filling conditions improve. 4, to improve discharge overflow conditions, increasing overflow traffic. 5, to improve injection speed, better ventilation conditions. 6, higher than the pressure if necessary, please call: 0317-8039866 http://www.ruitaiyz.com
