Embodiment Construction

[0024] Such as figure 1 and figure 2Shown is a liquid riser 2 for transporting molten metal, the liquid riser 2 includes a substantially tubular frame body 20, and outer and inner surfaces of the frame body 20 are respectively coated with outer thermal insulation coating 21 and inner thermal insulation coating 22; the mechanical strength of the skeleton body 20 is greater than the mechanical strength of the outer thermal insulation coating 21 and the inner thermal insulation coating 22; the outer thermal insulation coating 21 and the inner thermal insulation coating 22 It is a thermal insulation mineral mixture, which includes alumina, talc, mica, diatomaceous earth and titanium oxide.

[0025] The structure of the liquid riser applying the technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the skeleton body 20 is roughly tubular, and an upper tube hole 201 is arrang...

Abstract

The invention relates to a liquid lifting pipe for conveying molten metal for casting and a casting mold applying the liquid lifting pipe. The liquid lifting pipe is characterized by comprising a framework body approximately in a pipe shape, wherein concave and convex regions are arranged at the inner side and the outer side of the framework body respectively; an inner heat insulation coating and an outer heat insulation coating are respectively applied and attached onto the concave and convex regions arranged at the inner side and the outer side; the mechanical strength of the framework body is greater than that of the heat insulation coating and the inner heat insulation coating; each of the outer heat insulation coating and the inner heat insulation coating is a coating prepared from heat insulation ore mixed materials; the coating is prepared from aluminum oxide, talcum powder, mica, diatomite and titanium oxide. Therefore the maintenance of the liquid lifting pipe is convenient; the service life of the liquid lifting pipe is prolonged.

Description

technical field [0001] The invention relates to an accessory applied to a casting mold, in particular to a liquid riser for conveying molten metal. Background technique [0002] The riser pipe is a transition delivery pipe installed between the casting cavity and the molten liquid storage cavity, and is used to transport the molten metal in the molten liquid cavity to the casting cavity for casting of metal castings . At present, the more common riser pipes are generally steel pipes, iron pipes or ceramic pipes, but no matter whether they are steel pipes, iron pipes or ceramic pipes, the effect is not very satisfactory. The main reason is that the steel pipes and iron pipes have high thermal conductivity. poor effect. Although the ceramic tube has low thermal conductivity and good protection effect, it is relatively easy to be damaged during use. The broken ceramic fragments will pollute the molten metal and affect the quality of the metal casting, and it is also very easy...
