Precautions:
The filter should be placed on the lane closer to the separation cavity, so that there can be more floating sand in the lane.
The filter is recommended on the typical surface of the pouring track, so that the operation is simple and the effect is good. At this time, the lane in the direction of the water is on the box as much as possible, which is conducive to the floating of the mixed objects and reduce the resistance to the iron water.
When the lane cannot be overlapped for some reasons, the filter can be placed on the horizontal section of the horizontal or inner waterway. At this time, the lane must be on the box. Because the mixed objects flow in the upper part of the metal solution, the lower gap of the net does not affect the residue blocking, but when the cross -sectional area of the lane is too large or too wide, the filter will be deformed at high temperature, causing the lower gap to be too large and affecting the slag resistance effect.
The placement of the filter in the pouring system should be fixed and reliable to prevent the shock of the metal liquid and affect the slag resistance effect. Generally, the section of the filter-type sand-type pressure edge is: 15mm per side of the wet water pouring system. If it is buried in the lane, each side can be slightly smaller, and the dry type per side is 20-30mm.
The advantage of using filters:
Can greatly reduce defects such as slag, sandy eye, and pores, and reduce the casting rate of casting
Improve the production rate of casting process and reduce the amount of casting processing, improve the cutting performance
Improve the mechanical performance of casting
Simplify the pouring system and save metal
