Abstract

The utility model discloses a tin groove bottom component with surface treatment, comprising a tin groove body formed by welding a tin groove export chiladium with a groove bottom steel plate, bolts and nuts used for fixing a groove bottom brick in the tin groove, wherein, the inner wall surface of the tin groove export chiladium and the surface of the bolts and nuts to fix a groove bottom bricks in the tin groove are covered with a protection layer. The utility model is solid and durable, has strong anti-erosion ability, effectively avoids low temperature common melt caused by a touch of tin liquid and metal components and prolongs service life of a kiln.

Description

Have surface-treated molten tin bath bottom land member

The utility model relates to the molten tin bath bottom land member of using in the float glass, mainly is that prior art constructions has been done improvement.

In float glass, though molten tin bath bottom land metal construction directly do not contact with tin liquor because the density of tin liquor is big, molten some low-permeability is extremely strong, can contact with the bottom land hardware by the infiltration of the slit between the bottom land, produce low-temperature eutectic, the attack metal member.

At present, the bottom land hardware of float glass tin bath all end adds any protection, just it is cooled off, and brings following problem like this:

1, not having air-cooledly in tin bath outlet labial lamina portion, mainly is to cool off with purity nitrogen, though the producer that has has added water-cooled, though temperature is not high herein, but cooling performance is poor, is in gas, liquid, solid attitude three-phase intersection simultaneously, and the outlet of molten tin bath labial lamina is subjected to erosion in various degree, the phenomenon of tin appears leaking, to the cooling of this problem as having taked to add water-cooled, having strengthened purity nitrogen, water directly cools off end plate etc., but poor effect, and sheet glass is caused serious quality problems, the maintenance of have to being forced to stop production.

2, when the bottom land brick was installed, stud weld was connected on the bottom land steel plate, and end brick is fixed by bolt, nut, beat reality with the sealing of hole material,, easily cause the junction stannize because the composition material of end brick and sealing of hole material differs, this just may corrode bolt, nut, because after the end brick nephelinization layering, end brick come-up, thicker as supernatant, expose bolt, nut, tin liquor directly corrodes, and the time one is long, bolt or nut have been etched, and can cause bigger accident to take place.

The purpose of this utility model provides a kind of surface-treated molten tin bath bottom land member that has, and by relevant bottom land member is protected, can effectively prevent the congruent melting between tin liquor and the member, has slowed down the erosion of tin liquor to member.

For achieving the above object, the technical solution of the utility model is finished like this:

A kind of surface-treated molten tin bath bottom land member that has, it is in the inner wall surface of the tin bath outlet labial lamina of original molten tin bath bottom land member and is used for fixing the bolt of bottom land brick, the surface coverage matcoveredn of nut; The thickness of its protective layer is 0.1mm-0.8mm.

Above-mentioned protective layer is a kind of ceramic body, adopts the method for high-temperature injection that it is combined on the bottom land hardware securely, has improved erosion-resistant ability.

The utlity model has following characteristics:

1, on floatation glass production line; selected the bolt simultaneous test of brick at the bottom of the pickup groove for use; it is had protective layer through the surface and last surface treated bolt was put into molten tin bath after 10 hours, last surface treated bolt corrodes with respect to the surface treated diameter of bolt and has reduced 1/2.

2, need not make any change or otherwise designed to the structure formation of existing bottom land member, only the bottom land member be carried out surface treatment, because of stupalith not with metal reaction, therefore do not influence the use properties and the one-piece construction of molten tin bath.

3, to have corrosion resistance strong for this ceramic coating, stable performance, the advantage that the life-span is long.

4, supercoat can be implemented surface treatment according to working condition more conveniently when making or install.

5,, do not influence operation and install, and when cold repair, do not need particular processing because supercoat is thinner.

Do detailed explanation below in conjunction with accompanying drawing embodiment:

Fig. 1 is for having member synoptic diagram at the bottom of the surface-treated molten tin bath.

Have a member at the bottom of the surface-treated molten tin bath by shown in Figure 1; it is welded into the molten tin bath body by tin bath outlet labial lamina 1 and bottom land steel plate 3; and on the bottom land brick of installing on the bottom land steel plate 34, pass through bolt 5; nut 6 and member at the bottom of the bottom land steel plate 3 fixing formation molten tin baths; in order to solve the erosion of bottom land member; and in the inner wall surface of original tin bath outlet labial lamina 1 and be used for fixing the bolt 5 of bottom land brick 4 and the surface coverage matcoveredn 2 of nut 6; this protective layer 2 can adopt stupalith; the thickness of its surface-treated protective layer 2 is 0.1mm-0.8mm; the formation of its protective layer 2; the method that can adopt high-temperature injection to handle; make it to form not the ceramic layer with metal reaction, have firm; durable; the effect that corrosion resistance is strong.

The treatment process of this ceramic protective layer 2 is included in when the bottom land member is made carries out surface treatment, or carries out surface treatment when molten tin bath is installed, and can and make things convenient for situation to decide according to construction.

Except that being coated with on member at the bottom of the above-mentioned molten tin bath the application form of ceramic protective layer 2, this surface-treated protective layer can also be used on the associated metal member that contacts with tin liquor.

The application of described ceramic protective layer 2 need not change original bottom land member and structural shape, can make according to common design, can not influence one-piece construction.

Claims

1, has surface-treated molten tin bath bottom land member; comprise the molten tin bath body that tin bath outlet labial lamina and bottom land steel plate are welded into; and bolt, the nut of brick at the bottom of at the bottom of the pickup groove, it is characterized in that: it is by the inwall of tin bath outlet labial lamina (1) and be used for fixing the bolt (5) of bottom land brick (4) and the surface coverage matcoveredn (2) of nut (6).
