Problems solved by technology

Since most of the current cooling staves are made of wood, the size is very flexible, and special tools are not used to check and control the shape, and the dimensional tolerance is difficult to control, which affects the quality of the bricks.

Embodiment

[0059] Sample for checking the size of the stave wooden formwork brick groove:

[0060] 1. To make a duplex model, the material is 3mm thick steel plate, which is processed by CNC machine tools.

[0061] The double-joint model structure is Π-shaped, the width of the upper part is W, the inner height H1, outer height H2, inner width D1, outer upper width D2, outer lower width D3 of the lower part, where:

[0062] W=2a+20;

[0063] H1=h+20;

[0064] H2=h * (1+ wooden formwork extension chi)+2;

[0065] D1=(a+1)×(1+ wooden formwork extension ruler);

[0066] D2=(a+1+n)×(1+ wooden formwork extension ruler)-0.2;

[0067] D3=(a+1+m)×(1+wooden mold extension ruler)-0.2;

[0068]Among them: m is the width of the upper end of the brick inlaid groove, n is the width of the lower end of the brick inlaid groove, h is the depth of the brick inlaid groove; the wooden mold extension ruler is the pattern magnification rate, or the casting line shrinkage rate; all dimensions are in mm.

Abstract

The invention relates to a cooling wall wood mould brick inlaid slot dimension inspection template and a use method. The template comprises a double link template and a single link template. The double link template is made of a steel plate and has a n-shaped structure of which the width of the upper part is W, internal height of the lower part is H1, external height is H2, internal width is D1, external upper width is D2 and external lower width is D3. The single link template is made of the steel plate and has a T-shaped structure of which width of the upper part is L, height of the lower part is H, width of the lower part is S1 and width of the bottom part is S2. Distance between any two adjacent brick inlaid slots is inspected by the double link template, and the dimension of the single brick inlaid slot is inspected by the single link template. After application of the inspection template, precision of the cooling wall wood mould brick inlaid slot dimension is significantly enhanced, efficiency of wood mould manufacturing is enhanced, and the design requirement of cooling wall finished brick inlaid slot dimensional tolerance is met. After application of the template, the brick joint is uniform and strength and flatness are enhanced after a firebrick is inlaid in a cooling wall. The phenomenon of firebrick shedding does not occur in the installation, lifting and use process of the cooling wall.

Description

technical field [0001] The invention relates to an inspection tool for cooling equipment of an ironmaking blast furnace, in particular to a sample for inspecting the size of a stave wood formwork brick groove and a using method thereof. Background technique [0002] At present, most of the cooling stave products used in domestic and foreign ironmaking blast furnace cooling equipment are castings, which are formed by casting seamless steel pipes-cooling water pipes into the body. Except for the cooling wall at the lower hearth of the blast furnace, the rest of the cooling wall is inlaid with refractory bricks or rammed refractory materials to protect the cooling wall from being directly baked by high-temperature molten iron, which will affect the service life and reduce the heat loss of the blast furnace. Due to the poor strength of ramming refractories, very few are used now, and almost all of them are cast and inlaid bricks. Thereby the quality of inlaid brick directly aff...
