Method and iron scraping device for removing iron sticking in sand box of cast iron molding and pouring production line

Abstract

The invention discloses a method for removing sticking iron of a sand mould box of an iron casting moulding and pouring production line and an iron scraping device of the method. The method includes the following steps: firstly, mixing a refractory material, a binder and water with high-speed uniform stirring to form slurry type coating; secondly, brushing the two sides of the top face of the cope sand mould box with the coating well stirred; finally, mounting the iron scraping device behind a pouring station, so that when the sand mould box with the sticking iron passes the device, the sticking iron can be cleaned and removed by iron scrapers on the iron scraping device to guarantee normal running of the moulding and pouring production line. By the method, the coating well stirred is brushed on the two sides of the top face of the cope sand mould box to play a role in protecting the faces of the sand mould box, and accordingly the sand mould box is prevented from being sintered by high-temperature molten iron; the iron scraping device is mounted behind the pouring station, so that when the sand mould box with the sticking iron passes the device, the sticking iron can be cleaned and removed by the iron scrapers on the iron scraping device to guarantee normal operation of the moulding and pouring production line.

Description

technical field [0001] The invention relates to the field of molding and pouring of iron castings, in particular to a method for removing iron sticking in a sand box of a molding and pouring production line of iron castings and an iron scraping device thereof. Background technique [0002] At present, in the automatic production line of cast iron molding and pouring, since the casting molding and pouring process are automatically controlled by the program, it is inevitable that the accuracy of equipment positioning, the replacement of casting models and the clogging of the pouring port filter will inevitably cause problems during casting casting. Pouring molten iron splashes or overflows, thereby sticking to the surface of the sand box. However, since the sand box with residual iron bonded is not conducive to the sand making and cycle operation of the automatic molding line, a detection device for the residual iron bonded to the sand box will be installed on the molding line...

[0002] At present, in the automatic production line of cast iron molding and pouring, since the casting molding and pouring process are automatically controlled by the program, it is inevitable that the accuracy of equipment positioning, the replacement of casting models and the clogging of the pouring port filter will inevitably cause problems during casting casting. Pouring molten iron splashes or overflows, thereby sticking to the surface of the sand box

However, since the sand box with residual iron bonded is not conducive to the sand making and cycle operation of the automatic molding line, a detection device for the residual iron bonded to the sand box will be installed on the molding line. When the detection device senses the residual iron in the sand box , the molding line will automatically alarm and stop. At this time, the staff at the post must go through chiseling or even grinding to remove the residual iron on the surface of the sand box, which not only affects the production efficiency, but also greatly increases the work of the staff at the post. quantity
