Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification sheets and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or integral part, and do not get rid of other element or other integral part.
As shown in Figure 1 to Figure 2, be cavity according to the creepage rate device of the specific embodiment of the invention, its inner side at housing 1 is built two-layer refractory brick, forms the sidewall 2 of the inner chamber of creepage rate device.The bottom surface of inner chamber is built from bottom to top successively the flat half piece of brick of one deck and one deck T-3 brick, forms the bottom 7 of inner chamber.The local of bottom 7 is provided with step 3, makes to surround iron liquid hole 5 between bottom 7, the sidewall of step 3 and the sidewall 2 of inner chamber, and the end face of step 3 is provided with groove, forming reactions nest 4.The opening part of creepage rate device is provided with mouth 6, and mouth 6 is made up of moldable.
Preferably, sidewall 2 is inclined-planes, and gradient is 10 ° to 15 °.
Preferably, on step 3 towards iron liquid hole 5 side be inclined-plane, gradient is 40 ° to 60 °.
Preferably, iron liquid hole 5 is up big and down small conical socket, and its overall dimension suitable for reading is 300mm*180mm, and the overall dimension of bottom surface is 260mm*160mm, is 160mm deeply.
Preferably, mouth 6 is in " U " shape.
The method making this creepage rate device is as follows:
1, with clay pulp-water brushing housing 1, more two-layer flat half piece of refractory brick formation sidewall 2 is built.Refractory brick length is to edge-on, and refractory brick surrounding coats soft daubing mud, and the gap of refractory brick is alternately arranged, and gap is less than 2mm.
