Chinese foundry “Jilin Province Boqiang Machinery Manufacturing Co., Ltd.” successfully started up their new automatic moulding line with the automatic pouring unit MGM-PU 100 supplied by the German company Muschna Giesserei-Maschinen GmbH, Bad Laasphe.
During fully automatic pouring of moulds from a 1 ton ladle a new approach to the pouring process is used. The pouring curve follows a mathematic calculation on basis of gating system data, metal absorption capacity of the mould as well as pouring weight.
By this, the pouring process achieves a very high precision and the slow down and stop of pouring on the end of the pouring process is very smooth. The usual lengthy set-up when introducing an automatic pouring is omitted, so that the start-up period has been significant shortened.
The visual camera control of the metal level in the pouring cup is used just for confirmation of exact pouring execution and as safety control during pouring. Inoculation into the pouring stream occurs by volume dosing on basis of the pouring curve.
