Iron water tank with slag filtering function

A first partition plate and a second partition plate are sequentially arranged in a tank body from left to right, a first passing opening is formed in the lower side of the first partition plate, a second passing opening is formed in the lower side of the second partition plate, and a third passing opening is formed in the lower side of the second partition plate. Mounting grooves are formed in the middle positions, between the first partition plate and the second partition plate, of the front side wall and the rear side wall in the tank body, and a slag filtering plate is arranged between themounting grooves in the two sides. By means of the device, molten iron cannot directly flow to the slag filtering plate to impact the slag filtering plate, the service life of the slag filtering plate is prolonged, meanwhile, secondary filtering can be conducted on the molten iron, heat preservation and heat insulation can be conducted on the molten iron through layered arrangement of the groovebody of the device, the so
