Embodiment Construction

[0010] Such as figure 1 The cut-off ram shown is made of heat-resistant steel, and the components and elements in the heat-resistant steel are calculated by mass percentage: Cr 15-30%; Ni 65-81%; C 0.15-0.25%; S 0.001- 0.03%; Si 0.2-1.5%; P 0.001-0.05%; Mn 0.5-1.0%; Mo 0.6-0.9%; V 0.2-0.4%; Cu 0.5%. Satisfied that the cut-off ram can withstand high temperature above 1200°C, and has a low expansion coefficient (18.0×10-6 / °C).

[0011] Such as figure 2 As shown, the thickness of the upper part of the closure ram is greater than that of the lower part, and the surface is inclined. The height of the ram is between 400-500mm, the width of the upper part of the ram is 60-70mm, and the width of the lower part of the ram is between 25-35mm. The board will not bend, deform or break under the environmental changes at room temperature and high temperature.

Abstract

The invention discloses an intercepting flashboard made of heat-resistant steel. The heat-resistant steel comprises the following elements in percentage by mass: 15-30% of Cr, 65-81% of Ni, 0.15-0.25% of C, 0.001-0.03% of S, 0.2-1.5% of Si, 0.001-0.05% of P, 0.5-1.0% of Mn, 0.6-0.9% of Mo, 0.2-0.4% of V and 0.5% of Cu. The thickness of the upper part of the intercepting flashboard is more than that of the lower part, and the surface is inclined. The intercepting flashboard can resist high temperature up to more than 1200 DEG C and has a low swell factor (18.0*10-6/DEG C). Because the special upper part of the intercepting flashboard is thicker than the lower part and the surface is inclined, the flashboard can be ensured not to bend, deform and break when the environment changes at normal temperature and high temperature.

Description

technical field [0001] The invention relates to a shut-off ram, in particular to a high-temperature-resistant and low-expansion shut-off ram. Background technique [0002] At present, in the ultra-clear rolled glass industry, there are many kinds of dams, some made of brick, and some made of refractory mud. It is easy to deform in a high temperature environment, resulting in the outflow of glass water, which is not conducive to safe production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shut-off ram with high temperature resistance, low expansion and no deformation. [0004] In order to achieve the purpose of the present invention, the technical solution of the present invention is: a dam, the material of which is heat-resistant steel, and the components and elements in the heat-resistant steel are calculated by mass percentage: Cr 15-30%; Ni 65 ~81%; C 0.15~0.25%; S 0.001~0.03%; Si 0.2~1.5%; P 0.001~0.0...
