The material that anode steel jaw protection against corrosion, the anti-oxidation major issue facing are guard rings (layer) is selected problem.In numerous alternative known materials, preferably any or which can reach the integrated protection effect (do not pollute the protection effect that ionogen sodium aluminum fluoride had again and have high heat shock resistance and mechanical impact property) of anode steel jaw the best, be the thorny problem that aluminum electrolysis industry faces always.
Anode steel jaw protection against corrosion, anti-oxidation another major issue facing be, between above-mentioned existing guard ring (layer) and anode steel jaw body to be connected (structure) very unreasonable.The every circulation primary carbon protective ring of anode steel jaw or aluminum oxide powder guard ring must be reinstalled.CN103183973A corrosion-resistant finishes is also additional protective layer after the moulding of steel pawl, and stability consistence is poor when its vitreous layer industrialization, must take recoat or coating depending on the situation of peeling off in the every circulation primary of anode steel jaw.This has greatly increased the smelting cost of electrolytic aluminum.
Summary of the invention
The utility model solves existing electrolytic aluminum anodic steel claw because the selection of guard ring (layer) material is improper thereby the poor problem of comprehensive anticorrosive, oxidation-protective effect of anode steel jaw; and owing to being connected the problem that (structure) is very reasonable, need to repeat to install and be coated with thereby greatly increased electrolytic aluminum smelting cost between guard ring (layer) and anode steel jaw body, provide a kind of novel corrosion resistant anode steel jaw.
The utility model is to adopt following technical scheme to realize: novel corrosion resistant anode steel jaw; comprise anode steel jaw body and the guard ring (layer) that is connected in the perishable position of anode steel jaw body is set, described guard ring is rare earth multicomponent metallic cementation guard ring or Hastelloy guard ring altogether.The utility model optimizes the common metallic cementation material of rare earth multicomponent and Hastelloy material makes guard ring, has greatly increased protection against corrosion, the oxidation proof properties of anode steel jaw.
Described rare earth multicomponent altogether metallic cementation material is the known materials of existing maturation; Certainly, Hastelloy is also known materials.Rare earth multicomponent altogether metallic cementation material at least has detailed introduction in following document:
1, rare earth and carbon and nitrogen atoms ooze and microalloying new theory [material heat treatment journal, in July, 2011, Liu Zhiru etc.] altogether.
2, the tissue of rare earth on kinetics of carburising and converted steel and the impact of performance [rare earth, the 6th phase in 1986, Wang Rui etc.].
3, the impact [sufacing, 2011 year April, Yu Yucheng etc.] of rare earth adding quantity on 20# gear steel microstructure and wear resisting property.
4, the impact of the corrosion resistance nature of rare earth on 20 steel and 45 steel surfaces [China rare earth journal, in March, 1993, the 11st the 1st phase of volume, Xu Yue etc.].
5, the impact [metal heat treatmet journal, 1993 year September, 14th volume 3rd phase, Liu Zhiru etc.] of rare earth low temperature high carbon potential carburizing on 20CrMnMo structure of steel and performance.
Further, guard ring is connected on anode steel jaw body with composite casting setting, is more specifically connected on anode steel jaw body with casting method with the vanishing pattern setting.Described composite casting (comprising casting method with the vanishing pattern) is existing currently known methods, taking casting method with the vanishing pattern as example:
1, select lost foam casting steel pawl, position that will complex protection ring when pre-formed white mould model is reserved out.After model baking operation completes, the guard ring (part 2 in Fig. 3,4) that passes through the operation decontamination processing such as shot-peening, pickling, oven dry is fixed on to the corresponding position of the white mould of steel pawl (part 3 in Fig. 3,4) claw.Model and circular guard ring close contact, after model group installs into, brushing lost foam paint is also dried.
2, the model after drying is imbedded to moulding in sandbox, select suitable pouring technology: increase strain relief, improve teeming temperature, alloy protecting ring and steel pawl are fused together.
Guard ring and anode steel jaw body are combined as a whole in steel pawl casting process; make connection between the two tightr; once shaped is used until scrap and do not need to process again, has not only simplified the process that anode steel jaw recycles, and has greatly reduced cost.
