ABSTRACT:
A compact lance, for tuyeres. The lance provides a compact and secure holder by providing a bushing between a collet chuck and a gasket sleeve. This bushing can move axially inside an inner hole of the handle, but cannot rotate in the hole. The bushing acts on the collet chuck to keep it immobile. Twisting of the tuyere is prevented by a slot in the bushing, a radial hole in the handle and a locator screw. By turning the locator screw down to the outer jacket of the tuyere, there is a fastening of the tuyere inside the tuyere holder. There is also a gas and slag holdback valve in the handle and a streamlined quick-action stop valve. A rapid closing valve is also provided and operated by means of an ergonomically designed operating lever.
