Embodiment Construction

[0019] A construction method of electric fused AZS or electric fused corundum bricks for an all-oxygen glass melting furnace, which includes:

[0020] Step 1, set up the mobile arch; see figure 1 , the movable arch frame includes an arched tire frame 1, the top of which is screwed into the adjusting bolt and covers the arc plate, and placed on two mobile frames 5 connected together with bolts 4, the The bottom support of the mobile frame is supported by a jack 6, and is connected with a directional wheel 7;

[0021] Step 2: Use special steel arch tires during masonry. There are 4 adjustment screws on each brick of the steel arch tires. The screws are fixed according to the size of single and double rows. Through adjustment, the arch height reaches the assembly height and meets the requirements of the stitching line;

[0022] Step 3: According to the pre-assembly drawing, the number of each ring brick is transported to the kiln successively by hydraulic trolley from both sides...

Abstract

The invention relates to a full-oxygen glass melting furnace. A construction method of electric melting AZS (alumina-zirconia-silica) or electro melting corundum brick crowns of the full-oxygen glass melting furnace comprises the steps that a movable falsework is erected; bricks are sequentially transported to the two sides in the furnace; during mounting, spacings between skew bricks and springer beams are adjusted from the skew bricks on the two sides; the bricks behind skews are sequentially mounted from left to right; the bricks with faulting or position unconformity can be hammered by a raising hammer, or moved by a crowbar; when the last three seal bricks are mounted, spacings between the upper surfaces and the lower surfaces of the bricks are measured; any error is adjusted timely; or when a seal position is 1mm smaller, hammering is performed by a wooden hammer during sealing; each crown comprises five or seven rings; each crown is designed with an expansion joint; after one crown is built up, the dimension of the whole crown is detected, the chord length and the arch height of each crown are recorded, and compared with data provided by pre-assembly, and rectification is performed timely if any problem; and construction is accomplished. The construction method is convenient to construct, and the assembly quality can be ensured.

Description

technical field [0001] The invention relates to an all-oxygen glass melting furnace, in particular to a method for constructing a large wall of an all-oxygen glass melting furnace. Background technique [0002] The structure of the so-called oxy-glass melting furnace is similar to that of a unit kiln. It adopts oxy-fuel combustion technology, and its combustion does not require reversing. The mild and stable kiln pressure is beneficial to the melting and clarification of the glass, and reduces the bubbles, gray bubbles and streaks in the glass. It can be said that it is the second revolution of the glass furnace. The oxy-fuel glass production line realizes energy saving, consumption reduction, pollution reduction, and significantly improves glass quality. Its technology meets the requirements of my country's energy saving and environmental protection. Looking forward to the future, the application prospect of oxy-fuel combustion technology in glass furnaces is bright. [...
