Abstract
The present invention discloses a high-silicon composite fire-retardant spattering-resistant tube and a manufacturing method thereof. The manufacturing method has the key point that the external surface of a paper casing tube is firmly coated with one refractory material layer prepared from kieselguhr as a main component. The manufacturing method comprises: taking 85 to 95% of kieselguhr with the SiO2 content of 80% or so; adding an amount of auxiliary components containing AL2O3, and binding agents; stirring, thoroughly mixing, introducing the mixture into a photoelectrically controlled extrusion apparatus, and firmly coating the refractory material on the external surface of the paper casing tube via a vacuum extrusion procedure; and finally, drying at certain temperature for a certain period of time to obtain the high-silicon composite fire-retardant spattering-resistant tube. The manufacturing method not only prolongs temperature measurement time and improves the measuring accuracy of liquid steel, but also increases the temperature of measurable liquid steel to 1700 DEG C; the spattering of the liquid steel can be prevented when a thermocouple is used for contact measurement.
Description
Technical field
The present invention relates to a kind of flame-proof thermal insulation material goods, particularly a kind of high-silicon composite fire-retardant spattering-resistant tube of measuring liquid steel temperature under the molten state, protection thermopair when being used to make steel.
Background technology
Steelworks often needs to be grasped and adjusts the temperature of molten steel under the molten state when producing.The control of invar water temp is directly connected to the quality of product, is related to production cost.And under the molten state steel, iron temperature more than 1200 ℃.For reaching required measuring accuracy, the metallic thermocouple thermometer of contact commonly used is measured.This kind mode is simple, reliable, can reach required observed value.But because liquid steel temperature is too high, the Measuring Time of prior art can only reach 3-4 second, so thermometric tolerance range is not very high.And the thermal shocking of the iron and steel generation under the normal temperature thermopair contact molten state down when measuring also can cause splashing of molten steel, influences operative employee's safety.
Summary of the invention
Order of the present invention is not high for solving when utilizing the metal thermoelectric pair-point to survey liquid steel temperature in the prior art the too short precision that causes of Measuring Time, and can cause the shortcoming of splashing of molten steel and provide a kind of and can prolong more than thermometric time to 6 second, prevent the thermopair safety guard that molten steel splashes.
The present invention is achieved in that at the compound securely one deck in papery telescopic outside be the refractory masses of main component with diatomite.Its making method is to get SiO
2Content is about 80% diatomite 85-95%, adds an amount of AlO that contains
3The batching of composition and binding agent, through stirring, allow the evenly laggard extrusion equipment of going into photoelectric control of its thorough mixing, make refractory materials be compounded in papery telescopic outside securely, promptly become high-silicon composite fire-retardant spattering-resistant tube through certain temperature and the oven dry of time again through the vacuum extrusion operation.A high-silicon composite fire-retardant spattering-resistant tube made from aforesaid method putting on the thermopair of direct contact molten state molten steel more than can prolong thermometric time to 6 second, improve the accuracy that molten steel is measured, and can prevent that molten steel from splashing, improve stokehold thermometric workman's labor condition.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is a manufacture craft schema of the present invention.
Embodiment
In conjunction with Fig. 1, Fig. 2, Fig. 3, it is main raw material that outer high temperature material 1 adopts diatomite, presses diatomite 95% then, contains AlO
3The SILICA FUME 3% of composition, binding agent 2%.The main component of binding agent is water glass (water glass).Stir in reserves are 10 kilograms agitator, churning time is 20-30 minute, and the batching metering permissible error is 0.1kg.With the extrusion equipment of the raw material that stirs input,, be that paper tube 2 skins are the composite product of high siliceous refractory [material 1 thereby form a kind of internal layer by vacuum extrusion and paper tube 2 compound once shapeds with photoelectric control.Product after the moulding is placed on the drying plant, temperature is controlled at 40-50 ℃, through 10-20 hour oven dry aftershaping.Get final product through checking, packing after product is qualified.
The present invention has not only prolonged the thermometric time, improves the accuracy that molten steel is measured, and also can survey
The present invention has not only prolonged the thermometric time, improves the accuracy that molten steel is measured, and also can survey liquid steel temperature and bring up to 1700 ℃, can prevent that molten steel from splashing when using the thermopair contact detection.And the product after the moulding and paper tube combine closely, and do not come off, and do not ftracture, and has certain mechanical strength, anti-chilling, good in thermal property.In addition, product performance are stable, can long-term storage, and for the production and the use of enterprise provides convenience.
