US 5,632,937 A · Method of installing a refractory lining

Abstract

A method is provided for installing a refractory lining in a metallurgical vessel having a main opening which is much smaller than the diameter of the vessel. The method is especially useful in a vessel having a circular or otherwise curved cross-section. A form or mold is assembled inside the vessel, leaving a space between the form and the outer shell of the vessel. The form is supported on both sides, to maintain the distance between the form and the outer shell, and to prevent collapse or implosion of the form. Then, a pumpable casting composition having a smooth and easy flow is injected between the form and the shell, and allowed to harden. The use of the pumpable composition significantly shortens the time required to form the liner.

A method of assembling in situ a mold and installing a refractory lining in a torpedo vessel, comprising the steps of:

providing a torpedo vessel having an inside diameter and a main opening, the main opening having a diameter which is less than the inside diameter of the torpedo vessel;
installing an outer support mechanism inside the torpedo vessel;
installing a form inside the torpedo vessel at a distance from an inner wall of the torpedo vessel, with the outer support mechanism maintaining the distance between the form and the inner wall;
installing a hollow inner support mechanism on a side of the form which faces away from the inner wall;
pumping a refractory composition between the form and the inner wall;
and
hardening the refractory composition.
