1 A novel technology of soda-lead concentrates reverberatory furnace smelting is put forward according to the characteristics of copper dross with low sulfur and high copper content.

2 To line the hearth of(a reverberatory furnace) with loose sand or ore in preparation for pouring molten metal.

3 Up to date, reduction smelting in reverberatory furnace is the dominated method, but low recovery efficiency is a common problem in this process.

4 Replace the reverberatory furnace and gas producer etc. , there is no light fire producing when heating, and it accords with national fire protection safety rules.

5 The invention discloses a semi-vertical reverberatory furnace for preparing sodium sulfide and a technique thereof.

6 Fettle:To line the hearth of (a reverberatory furnace) with loose sand or ore in preparation FOR pouring molten metal.

7 The technics of the vertical furnace and reverberatory furnace is introduced in this paper.

8 The charging installations of fixed refining reverberatory for copper smelting generally use bridgecharger and ground charger with mechanical drive.

9 The semi-vertical reverberatory furnace comprises a combustion chamber, a forehearth part,[www.Sentencedict.com] a vertical furnace and an aeration tower.

10 According to the thermal process in reclaimed copper reverberatory furnace, the physical and mathematical simulation models were built.

11 The casted door brick for reverberatory furnace which introduced mullite grains has an obvious longer service life than the imported brick .

12 A kind of environmental protection fuel melting copper reverberatory furnace with spray nozzle is introduced.

13 The characteristics of double arch reverberatory furnace by coal-burning(DARFBCB) and the application results in zinc alloy smelting and zinc refining are described.

14 The recycling aluminum industry shall phase out coal fired reverberatory and other reverberatories under 4 tons and crucible furnaces are prohibited to smelt recycling aluminum alloy.

15 The technique of X-ray radiograph video was used to study the physical phenomena in experiments simulating copper matte smelting in reverberatory or electric furnaces.

16 This paper presents analysis and comparison of direct recovery rate and other technical parameters in crude tin reduction smelting between reverberatory furnace and Ausmelt furnace.

17 Loose sand or ore used to line the hearth of a reverberatory furnace in preparation for pouring molten metal.

18 The paper introduces how to select reclaimed copper pyrorefining furnace type as well as innovative approach to process flow of scrap pyrorefining by reverberatory furnace.

19 Slagging and blocking slag: This product can be used in ladle, crucible boiler[sentencedict.com], electric furnace and reverberatory furnace.

20 It introduces the process of recovering Indium from Lead reverberatory dust with H2SO4 leaching-P204 extraction.

21 The Mo recovery process was tested from the smelting slag of Bi reverberatory furnace by water quench leaching, and the tested process was compared with the present soda leaching process.
