Abstract
The invention provides a fast tempering process method for an air-pressure pouring furnace. The method is characterized by comprising the step A of calculating the volume of a furnace body; the step B of weighing molten iron and measuring the liquid level of the molten iron; the step C of carrying out correction; the step D of measuring the liquid level of the molten iron on an iron notch; the step E of compiling a fast look-up table. The method has the advantages that compared with an existing method, adjustment operation of the fast tempering process of the air-pressure pouring furnace is definite, molten iron ingredients are simple and easy to replace, molten iron temperature is simple and easy to change, the product replacing speed is high, and the production efficiency is improved.
Description
Technical field
The present invention relates to hardening and tempering process field, being specifically related to is a kind of press pouring furnace fast hardening and tempering process.
Background technology
When automatic mo(u)lding line adopts air pressure to have core insulated pouring stove to produce ironcasting, when producing different product, need chemical composition or the temperature of changing molten iron in press pouring furnace.When adopting according to weight of molten iron in the Pressure gauge numerical estimation pouring furnace that press pouring furnace fills, cause weight of molten iron deviation larger owing to accumulating more slag in pouring furnace stove, cause to change in pouring furnace hot metal composition or temperature more difficult, affect replacement of products and production efficiency raising.
Existing press pouring furnace hardening and tempering method, large according to weight of molten iron deviation in Pressure gauge numerical estimation pouring furnace, adjustment operation is indefinite, change hot metal composition or temperature more difficult, affect replacement of products and production efficiency raising.
Summary of the invention
For solving the problem, the invention provides a kind of press pouring furnace fast hardening and tempering process, it is characterized in that: comprise the following steps:
A body of heater volume calculations: measure furnace interior size when the new brickwork of press pouring furnace serves as a contrast, calculate body of heater volume, obtain initial calculation value;
B weighs weight of molten iron and molten iron level height: when press pouring furnace is enabled, before molten iron pours pouring furnace into first, weigh weight of molten iron and after pouring into, measure molten iron level height in stove, obtain the relation of weight of molten iron and liquid level in stove and contrast with initial calculation value;
C corrects: body of heater volume in press pouring furnace use procedure is because inwall accumulated slag reduces to some extent, use instrument and positioning tool measure furnace interior size and calculate body of heater volume, for correcting the relational expression of weight of molten iron and liquid level in stove when pouring furnace time-based maintenance;
D measures molten iron level position, iron mouth place: adopt radar material measurement amount press pouring furnace to enter Tie Kouchu molten iron level position, contrast molten iron level height and weight relationships formula thus accurately obtain weight of molten iron in pouring furnace;
E works out table of noting fast: the modified table of noting fast of establishment press pouring furnace, comprises the parameters such as the model of product, material and pouring furnace weight of molten iron, molten iron temperature.
The invention has the beneficial effects as follows: compared with the conventional method, press pouring furnace fast hardening and tempering technique, adjustment operation is clear and definite, and replacing hot metal composition or temperature are simply easy, and replacement of products speed is fast, production efficiency improves.
