Abstract
A furnace binding and adjustment system for maintaining a refractory furnace hearth under compression utilizes a plurality of buckstays connected at their upper and lower ends by tie members. A fluid-pressurized tensioning device, preferably a hydraulics device, is provided at the ends of at least some of the tie members to permit some relative movement between the tie member end and the buckstay to permit adjustment of compressive forces applied to the refractory hearth. The use of multiple hydraulic devices permits simultaneous activation of the tensioning devices, and also permits the hydraulic pressure in the cylinders to be accurately adjusted and monitored from a remote location.
Claims25
A furnace binding and adjustment system for a rectangular furnace having a pair of opposed sidewalls, a pair of opposed end walls and a hearth comprised of refractory bricks, said system comprising:
- a plurality of vertically extending buckstays arranged in spaced relation along each of the sidewalls and end walls of the furnace, said buckstays each having an inner face engaging one of said walls, an opposed outer face, and a lower end extending below the hearth, said buckstays being arranged in pairs with the buckstays of each said pair being positioned across the furnace from one another;
- a plurality of lower tie members, each having a first end and a second end and extending between the lower ends of a pair of said buckstays;
- and
- a plurality of fluid-pressurized lower tensioning means, each of said lower tensioning means being secured to a lower end of one of said buckstays and being connected to the first end of one of said lower tie members, each said lower tensioning means adjustably controlling an amount of tension in one of said lower tie members to thereby apply a controlled compressive force to the furnace.
A furnace binding and adjustment system for applying a compressive force to a furnace having a hearth and/or one or more sidewalls comprised of refractory bricks, said system comprising:
- (a) fluid-pressurized tensioning means;
- (b) a tie member having first and second ends, the first end attached to the tensioning means;
- (c) a retaining member to which the second end of the tie member is secured, wherein actuation of the tensioning means increases tension in the tie member between the cylinder and the retaining member;
- and
- (d) a support member for supporting said tensioning means;
- wherein said retaining member and said support member are spaced from one another with one or both of said retaining member and said support member being in compressive contact with said furnace;
- and wherein actuation of the tensioning means to increase tension in the tie member causes a corresponding increase in said compressive force.
A furnace binding and adjustment system for applying a compressive force to a furnace having a hearth and/or one or more sidewalls comprised of refractory bricks, said system comprising:
- (a) fluid-pressurized compression means in compressive contact with said furnace;
- (d) a support member for supporting said tensioning means;
- wherein said compression means are located between said support means and said furnace, such that actuation of said compression means causes an increase in the compressive force on the furnace.
