Embodiment Construction

[0030] Plate coolers are used to cover the inner walls of the shell of metallurgical furnaces, such as blast furnaces or electric arc furnaces. The purpose of this plate cooler is to form: (1) a thermal discharge protective barrier between the interior of the furnace and the outer shell; Anchoring device.

[0031] now refer to figure 1 , it will be noted that the plate cooler 10 has a panel-like body 12 made, for example, of a cast or forged body of copper, copper alloy or steel. This panel-like body 12 has a front face 14, also called hot face, which will face the interior of the furnace, and a rear face 16, also called cold face, which will face the inner surface of the furnace wall. The panel-like body 12 generally has the form of a quadrilateral having a pair of long first and second edges and a pair of short upper and lower edges. Most modern plate coolers have a width in the range 600 to 1300 mm and a height in the range 1000 to 4200 mm. However, it will be appreciat...

Abstract

A stave cooler for a metallurgical furnace, in particular for a blast furnace, including a panel-like body having a front face for facing the interior of the metallurgical furnace and an opposite rear face; and at least one internal coolant passage arranged within the panel-like body, where the at least one shaft, protrudes from the front face of the panel-like body.

Description

technical field [0001] The present invention generally relates to plate coolers for metallurgical furnaces. Background technique [0002] Such plate coolers for metallurgical furnaces are well known in the art. They are used to cover the inner walls of the shell of metallurgical furnaces, such as blast furnaces or electric arc furnaces, to provide: (1) a thermal discharge protective barrier between the interior of the furnace and the outer shell; and (2) refractory bricks for use inside the furnace An anchoring device for lining, refractory guniting, or process-generated build-up. Originally, plate coolers were cast iron plates with cooling tubes cast into them. As an alternative to cast iron plates, copper plates have been developed. Most plate coolers used in metallurgical furnaces today are made of copper, copper alloys or, more recently, steel. [0003] For example, German patent DE2907511C2 discloses a copper plate cooler for a blast furnace. It consists of a panel...
