Abstract
The invention relates to a mould, in particular to a mould for preparing a sampling hammerhead of a tuyere sampler of a blast furnace. The mould mainly solves the technical problems of poor moldability, low dimension precision, low density of a refractory material and low strength caused by low density of the refractory material of the sampling hammerhead existing in a cast mould. The invention adopts a technical proposal that the mould for preparing the sampling hammerhead of the tuyere sampler of the blast furnace consists of a movable pressure lever, an upper sleeve, a lower sleeve, a bottom board, a steel connecting pipe and ventilating orifice core rods, wherein the upper sleeve, the lower sleeve and the bottom board are spliced in sequence from top to bottom in a step mode; the movable pressure lever extends into the upper sleeve, the center of the bottom board is provided with an internal threaded hole; the steel connecting pipe with external thread is spirally connected to the inside of the internal threaded hole in the bottom board; two sides of the lower sleeve are provided with two parallel ventilating orifice core rods which extend into the steel connecting pipe through the lower sleeve; and the lower end face of the movable pressure lever and inner end surfaces of the upper sleeve, the lower sleeve and the bottom board form a cavity of the sampling hammerhead matched with the appearance of the sampling hammerhead.
Description
Technical field:
The present invention relates to a kind of mould, particularly a kind of mould for preparing sampling hammerhead of tuyere sampler of blast furnace.
Background technology:
Tuyere sampler of blast furnace is a kind of equipment that enters the blast furnace furnace inner sampling from the blast-furnace tuyere peep-hole.It is made up of water-cooling welding torch, water-cooling welding torch support and transmission mechanism, gas collecting device and some auxiliary water tubes, tracheae usually.Wherein water-cooling welding torch is a long steel pipe of water-cooled, is used for stretching in the stove from the air port taking a sample, and the air port sampling hammerhead has been installed in its end that enters in the stove.
As shown in Figure 1, 2, air port sampling hammerhead 2 in fact just is mounted in a kind of fire-resistant termination 6 that has breeder tube that can change in water-cooling welding torch steel pipe 1 head forward position.The pre-buried steel tube connector 3 of a threaded joint in this sampling head.Nipple is used for being connected of sampling hammerhead and water-cooling welding torch steel pipe 1, and breeder tube 5 then can import to furnace gas in the central duct 4 of embedded steel tube and water-cooling welding torch.
Furnace gas is under the effect of stove inner high voltage, and the central duct 4 by the breeder tube on the sampling hammerhead 5 enters water-cooling welding torch enters in the gas collector again, thereby reaches the purpose of collecting furnace gas and small injection material.
Air port sampling hammerhead common preparation method at present is: adopts wooden or steel die, cast expected that in the mould, material feeding is watered in tamping by hand then, and maintenance again, oven dry sampling head, standby.The air port sampling hammerhead that adopts this method to make is difficult for tamping, the anti-material of sampling hammerhead is not fine and close, the Forming Quality of breeder tube is poor, and the intersection point degree error of the axial line of the steel tube connector that the center is pre-buried and sampling hammerhead installed surface is big, thereby influences the intensity and the installation quality of sampling hammerhead.Not entering in the stove that quality is poor slightly just smashed by the high temperature wind energy, and be perhaps cracked in stove, and perhaps breeder tube is irritated slag or obstruction, causes and can't take a sample.
Summary of the invention:
The purpose of this invention is to provide a kind of mould for preparing sampling hammerhead of tuyere sampler of blast furnace, mainly solve the sampling hammerhead insufficient formability that adopts casting mold to exist, poor dimensional precision, anti-material density is low, and causes the low technical problem of intensity owing to anti-material density is low.
Technical scheme of the present invention is: a kind of mould for preparing sampling hammerhead of tuyere sampler of blast furnace, by movable depression bar, upper bush, lower sleeve, base plate, the steel tube connector, the breeder tube plug constitutes, upper bush, lower sleeve, base plate is splicing successively from top to bottom, splicing place is a step, movable depression bar stretches in the upper bush, base plate central authorities have internal thread hole, having externally threaded steel tube connector is screwed in the base plate internal thread hole, respectively there are two parallel breeder tube plugs to pass lower sleeve in the lower sleeve both sides and stretch into the steel tube connector, the lower surface of movable depression bar and upper bush, lower sleeve, the base plate inner face forms the sampling hammerhead chamber with sampling hammerhead profile coupling.
The invention has the beneficial effects as follows: adopt the special steel die of making, allow the pre-buried steel tube connector intersection point in sampling hammerhead center be fixed in the base plate of mould in the heart, guarantee that sampling hammerhead makes the axial line of back steel tube connector and the intersection point of sampling hammerhead installed surface; Adopt the method for high-pressure extrusion to improve the density of the anti-material of sampling hammerhead energetically, thereby improve the mouldability and the geometric accuracy of the anti-material of sampling hammerhead, reach the intensity that improves sampling hammerhead simultaneously.The anti-material of air port sampling hammerhead that obtains has good moldability, and is fine and close high, and easy to make, the efficient height of making.Because the quality that sampling hammerhead is made is good, anti-material intensity height, the anti-material of sampling hammerhead is non-friable when sampler is taken a sample, and has guaranteed sampler carrying out smoothly in the sampling of blast-furnace tuyere forward position.
Description of drawings:
Fig. 1 is a water-cooling welding torch end construction schematic diagram
Fig. 2 is an air port sampling hammerhead structural representation
Fig. 3 is a structural representation of the present invention
Among the figure: 1-water-cooling welding torch steel pipe, 2-air port sampling hammerhead, 3-steel tube connector, 4-central duct, 5-breeder tube, 6-fire-resistant termination, 7-movable depression bar, 8-upper bush, 9-lower sleeve, 10-sampling hammerhead chamber, 11-breeder tube plug, 12-base plate.
The specific embodiment:
With reference to Fig. 3, a kind of mould for preparing sampling hammerhead of tuyere sampler of blast furnace, by movable depression bar 7, upper bush 8, lower sleeve 9, base plate 12, steel tube connector 3, breeder tube plug 11 constitutes, upper bush 8, lower sleeve 9, base plate 12 is splicing successively from top to bottom, splicing place is a step, movable depression bar 7 stretches in the upper bush 8, the external diameter and upper bush 8 internal diameters of movable depression bar 7 are complementary, base plate 12 central authorities have internal thread hole, having externally threaded steel tube connector 3 is screwed in base plate 12 internal thread holes, respectively there are two parallel breeder tube plugs 11 to pass lower sleeve in the lower sleeve both sides and stretch into the steel tube connector, the lower surface of movable depression bar 7 and upper bush, lower sleeve, the base plate inner face forms the sampling hammerhead chamber 10 with sampling hammerhead profile coupling.
When carrying out the sampling hammerhead making, with the combination after mould place-steel framework in, adopt forcing press or a thousand pieces of gold top that the material feeding of watering of injecting in the mold is pushed, significantly improve the density of watering material feeding, thereby reach the mouldability and the geometric accuracy that significantly improve the anti-material of sampling hammerhead, reach the intensity that improves the anti-material of sampling hammerhead simultaneously.
