200th中厚板推鋼式連續(xù)加熱爐設(shè)計(jì)

摘要
本論文設(shè)計(jì)的是一座200t/h中厚板推鋼式連續(xù)加熱爐。加熱爐是在冶金、化工、機(jī)械制造等工業(yè)部門中，以燃料燃燒的火焰為熱源的各種工業(yè)爐的統(tǒng)稱。火焰爐廣泛應(yīng)用于物料的焙燒、干燥、熔化、熔煉、加熱和熱處理等生產(chǎn)環(huán)節(jié)，在鋼鐵冶金行業(yè)中占有非常重要的地位。隨著科技的發(fā)展以及人們對(duì)環(huán)境保護(hù)的要求，不管加熱爐怎樣變革，它總是要滿足優(yōu)質(zhì)、高產(chǎn)、低消耗、壽命長(zhǎng)、勞動(dòng)條件好等生產(chǎn)工藝。
本論文是在充分的查閱了相關(guān)資料，運(yùn)用了燃燒學(xué)、傳熱學(xué)、耐火材料、流體力學(xué)等專業(yè)基礎(chǔ)知識(shí)，并結(jié)合運(yùn)用了AutoCAD設(shè)計(jì)繪制了本加熱爐。

abstract
This paper the design is a 200 t/h pushed steel plate type continuous reheating furnace.
Heating furnace is in metallurgy, chemical, machinery manufacturing, and industrial sectors, with fuel burning flame as heat source of all kinds of industrial furnace collectively. Flame furnace are widely used in the materials roasting, dry, melting, melting, heating and heat treatment and other production link, in iron &steel metallurgical occupies very important position. With the development of science and technology and people to the requirements of environment protection, no matter how heating furnace changes, it is always to meet the high quality, high yield, low consumption, long life, good working conditions and production process.
The present paper is in full access to the related material, using the combustion science, heat transfer, refractory material, fluid mechanics, and other professional knowledge, and combined with the design using AutoCAD drawn the heating furnace

Keywords: Heating furnace Pushed steel type plate
