Gas Injection Mini

MINI HF

The MINI pump is a proven performer. With a small footprint the MINI is ideal for 10,000-50,000 pound furnaces. An easy addition to the MINI circulation pump is the patented foot and tube method of gas injection. This proven method will inject gas quickly and efficiently. The injection tube clamps easily to the motor mount, holding the tube and injection foot securely in front of the outlet of the base. As illustrated below, the gas flowing out of the pump outlet flows through the holes in the injection foot shearing the gas into tiny bubbles, improving the demagging performance.

The foot and tube is so easy to change, that the pump does not need to be pulled from the metal, decreasing down time.

Alternative Method

Problems with angled tube method:

¨ Tube projects into the flow of metal and is broken by debris passing through the pump.

¨ Large bubbles form on down-stream side of the tube and can break away when the metal flow is low.

¨ Only the top stream of metal shears gas. This requires faster metal flow to shear gas since half of the flow is not shearing.

¨ Gas leakage occurs between tube and plug.

¨ Build up of mag-chloride occurs in exit and reduces flow

Our Method

The gas injection tube and foot are clamped to the motor mount and the foot lines up directly in front of the outlet of the base. The velocity of metal flowing out of the base is pushed through small holes in the injection foot. This gas is sheared by the flow of metal and exits through the holes in the injection foot. The foot and tube are an easy to a Workhorse or MINI circulation pump.
